Correct Answer: D

Rationale: Pulmonary edema is the correct answer. It is a condition characterized by the retention of extra fluid in the lungs, often due to left ventricular impairment. This fluid buildup can lead to symptoms such as shortness of breath, coughing, and difficulty breathing. Whooping cough (Choice A), pneumonia (Choice B), and asthma (Choice C) are not conditions related to the retention of fluid in the lungs due to left ventricular impairment. Whooping cough is a bacterial respiratory infection, pneumonia is an infection that inflames the air sacs in one or both lungs, and asthma is a chronic respiratory condition characterized by airway inflammation and constriction.

Correct Answer: A

Rationale: The correct answer is Arm recoil. Arm recoil is slower in healthy but fatigued newborns after birth, making it best elicited after the first hour of birth when the baby has had time to recover from the stress of birth. This assessment helps evaluate neuromuscular maturity in newborns and is more accurate when performed after the initial recovery period. The other choices, Square window sign, Scarf sign, and Popliteal angle, are not specifically assessed using the Ballard gestational assessment tool and do not relate to the recovery period after birth.

Correct Answer: C

Rationale: The correct answer is C. Ear cartilage folded over, lanugo present over much of the body, and slow recoil time are all characteristics of a preterm infant. A is incorrect because full sole creases, nails extending beyond the fingertips, and scarf sign showing the elbow beyond the midline are features of a term infant. B is incorrect as testes located in the upper scrotum, rugae covering the scrotum, and vernix covering the entire body are also indicative of a term infant. D is incorrect because a 1 cm breast bud, peeling skin and veins not visible, and rapid recoil of legs and arms to extension are characteristics seen in a more mature infant, not a preterm newborn.

Correct Answer: A

Rationale: Breast engorgement occurs when the breasts become overfilled with milk. By increasing the frequency of feedings, the mother can ensure that her breasts are emptied regularly, helping to relieve the discomfort associated with engorgement. This advice promotes effective milk removal and prevents further accumulation, which can worsen the condition. Applying ice packs may provide temporary relief, but it does not address the underlying issue of milk accumulation. Avoiding breastfeeding can lead to further engorgement and potential complications. Using a breast pump to empty the breasts completely may be necessary in some cases, but increasing the frequency of feedings is the initial and most appropriate intervention to manage breast engorgement.

Correct Answer: A

Rationale: Hormones play various roles in the body, such as promoting growth and beauty, maintaining body temperature, and fighting infections. However, producing new offspring is not a direct function of hormones. Reproduction is primarily regulated by other factors like the reproductive system. Choice B is incorrect because hormones can indeed influence growth but not specifically 'beauty.' Choice C is incorrect as hormones can help regulate body temperature indirectly. Choice D is incorrect as hormones like cytokines can be involved in the body's immune response to fight infections.
